China Water Based Ink

Kagem food grade water based ink for napkin is an environmentally friendly and low odor water-based ink. It is mostly used in narrow flexographic printing and porous food packaging substrates, especially for paper towels and napkins. Under the conditions of high line number printing screen and high machine speed, it has excellent performance. At the same time, it has excellent performance in wear resistance and color.
Product features: it is non flammable, explosive, tasteless, harmless to human body and In line with VOCs emission standards. Our water based ink for napkin meets the environmental protection requirements of EU reach and FDA standards. It has excellent fluidity, good adhesion after printing, wear and scratch resistance, good water resistance, rapid drying and high definition.
Product uses: toilet paper, face tissue paper, napkin, diapers, sanitary napkins, wet tissue paper printing.

technical parameter
Viscosity: 15-30s / 1 4# cup of firewood, fineness: 鈮?15 渭 m at 25 鈩? pH: 8.0-9.0
Before use, it shall be fully stirred, filtered and reused. After opening, the ink storage shall be covered and sealed to prevent dust falling or crust drying. If it is found that the brightness or consistency is high, it can be adjusted with clean water or special diluent to avoid high temperature and hot sun exposure. Generally, the storage period is one year.
When using water-based ink, it shall be stirred evenly, and poured into the ink tank after measuring the appropriate viscosity. If the viscosity is not appropriate, it can be adjusted with diluent or thickener, and pay attention to controlling the pH value of the ink, which is generally controlled at 8.5 ~ 9.5. In the printing process, due to the volatilization of water, the viscosity of ink will increase and the pH value will decrease. Therefore, the use of ink should be observed frequently. When it is found that the viscosity of ink increases or the pH exceeds the control range, diluent and pH stabilizer should be used to adjust in time to ensure the stability of viscosity and pH value.
Water based ink for napkin is used for printing on food packaging in a variety of ways, such as printing on the outside of the cardboard box containing food, reverse printing inside the food packaging, and printing inserts in the packaging in contact with food.
Due to the diversity of uses – and therefore, there may be many different food contact scenarios – understanding the regulatory system applicable to printing inks is necessary not only for the companies manufacturing these inks, but also for manufacturers. Packaging materials and converters, as well as food manufacturers.
In the United States, the use of printing inks in food packaging materials is governed by laws and regulations administered by the U.S. Food and drug administration, including the federal food, drug and Cosmetics Act (“the act”). The act requires that these materials be manufactured under good manufacturing practices and that they are safe and suitable for the intended use.
Water based ink for napkin FDA as a food additive:
In addition to general manufacturing and safety requirements, other requirements may apply, depending on the intended use. Most importantly, if the use of water based ink for napkin causes the situation of “food additives”, the use must be included in the food additives regulations, effective food exposure notice (FCN) or regulatory threshold exemption letter; Otherwise, the use must be exempted from such permission.
Inks are usually composed of colorants, adhesives and carriers. Although according to 21 CFR 搂 178.3297 (“polymer colorant”) or 21 CFR 搂 176.170 (“composition of polymer”) if used in paper applications, there is no single regulation to determine the ink allowed for food packaging. Paper and paperboard in contact with food containing water and fat “). Colorants may also be permitted for their intended use according to regulatory exemption thresholds, prior sanctions or food exposure notifications.
The licensing of color additives for direct food applications should also be considered, because according to the licensing of color additives, it can be determined that color additives are also explicitly allowed for indirect applications, such as packaging. For example, 21 CFR 搂 178.3297 (d) clearly states that “according to the regulations on color additives, color additives and their lakes that can be directly used in food… Can also be used as colorants in food – contact polymers.”
Other components of water based ink for napkin may be the subject of separate “independent” regulations. For example, 21 CFR 搂 177.1520 (“olefin copolymer”) will cover polyolefin carriers for inks.
Even if there are clear provisions on each component in the ink in the food additives regulations, it is still necessary to consider whether the regulatory approval is suitable for the intended specific use. For example, high purity furnace black (hpfb) is specifically removed for polymers in accordance with 21 CFR 搂 178.3297, but hpfb is not specifically removed for paper. Consideration should also be given to whether regulations allow the use of a component in the resin. For example, CI pigment red 38 is specifically removed in accordance with 21 CFR 搂 178.3297 and can only be used for rubber. In addition, restrictions on food type, temperature and level of use may apply.
In other cases, customs clearance is not required?
Ink is not considered as a food additive when it is not reasonably expected that ink will become a food ingredient when used as expected. In this case, it is not necessary to determine clear regulatory licensing, such as food additive licensing, food exposure notification, regulatory exemption threshold, prior sanctions or gras status.China Water Based Ink
